Sometimes simple ideas lead to amazing results, and Lucas Zimmermann’s photo series “Traffic Lights” is a perfect example of that. Lucas started the project in 2013 but now he’s back with “Traffic Lights 2.0” and all of the images are oddly satisfying to look at.

“The possibility that light is “visible” in fog fascinates me,” Zimmermann said. “The unknown hue of blueish light is like the fog hidden for the human eye, but the photograph shows us things we otherwise overlook, such as a simple traffic light on the street. An all known object which produces a strong effect in an unnatural situation with a simple photographic setup.”

Lucas took the images on a foggy intersection near Weimar, Germany, late at night. He used 5-20 second-long exposure and slightly adjusted the color temperature in post production.
